axle mount

Product Q&A

Mounting a '32 Ford axle to a Model A frame. '32 rear end is 48.5" wide. I need 43-45" perch eye spacing, will it fit?
Note - picture shows stock Model A spring with the frame high on jackstands. I plan to use either a 910-43106, 910-4305 or 910-43107 spring. Car should be pretty light in the rear except when I have passengers in the back seat.

Part number 91645108 mounts in different locations depending on the spring used. If using the high arch spring with 39” eye center to center the Model A’s commonly use 46” perch centers and if using the medium arch the A’s commonly use 45” perch centers. The springs both require spreading to hook up to the shackles.

Does this kit require the useage of any type of modern shock kit or panhard bar when installed on a stock 1930 Ford Model A Sports Coupe frame using a Chevy 10 bolt positive traction or stock 1956 Ford F100 rear end?

This kit is simply the shackles and the weld on brackets to install a later rear end to your existing Model a cross leaf spring. You will still need to keep the rear end maintained in the stock location via the original wishbones, four bar, ladder bars, etc. Depending on the severity of use a panhard bar would extend the life of the four bar urethane bushings and keep the rear end centered. Shocks are always recommended and different brackets and mounts are available along with a wide variety of shock lengths that needs to match your ride height requirements.

The medium arch is a 2" wide spring and using kit 91645108 is designed for a 2 1/4" wide spring. You can shorten the bushings for the 2" spring and when installing on the shackles but a thick washer on both sides to make up the 1/4" difference. The medium arch spring is 5 1/2" shorter than the high arch when standing on the bench and measuring to the bottom of the arch at the top. The reversed eye gains one inch lower as well.
